After the'cutter and pin have entered the 'work the presser foot 49 isautomatically raised and the cutter head advanced one step, whereuponthe foot im 'is again lowered and the cutter head is@ raised andreturned to its normal -position ready for the next operation. Theinclined lower edge of the cutter tendsto urge the work downwardlyagainst the gauge Mi and tongue 31. However,

the operator keeps one or` both hands on the workand insures that itstays' in place. When the edge being trirnrnediis` concaveas in Fig.-12, or. convex, lthe operator not onlyholds the work in place. but alsoturns the Work in laccordance with the desired contouro'f theedge. Thismovement of the work takes place while the Acutter 4l and pin i3 areembeddediin: the work and feeding it, and to.` facilitate such trimmingthe cutter, mounted 'ec'centrically'on the Yhead 45.

`Itwill bevunderstoo'd that the-.punch bar 23 is so mounted that it :maybe oscillated rotatably about its vertical axis.. The `rneansfor somounting the bar are not here 'shown .or described, be-

cause/they are old .and well known inxmachines' of this type, asshownfor example in the Lautenschlager PatentmNo, 843,899, mentioned above.Thesizesof the notches dependy upon thelength of .thel vfeed step andmayrof course, be changed as desired. 'For example, the feed step whenmaking the edge shown in FigLilO, is longer than when making' the .edgeshown in' Fig. 11. for so varying the lengthI of 'the feed step are old`and. YWell-.knownin thisartand since this invention is not directedthereto, such mean-s have not been shown or describedin detail herein..Suitable means for .adjusting the'v lengthfof the feed stepTA areyshownandv described inthe Patent'to Lautenschlager No. 845,899,supra..Y See particularly Figs-2,13 and l of.` the drawings and theparagraph beginning at line 99 offpage' 1 oicthespeci'cation wherein`the adjustment of vthe bolt 49- in the arm d6 .for this purpose yis.set forth. l.

The essence ,of thisf invention resides in the combination with aprforating machine of an anvil provided with a base plate so formed thatthe Work `is held `at an :incline `.and the cutter of the machine formsinclined notches in the edgel ci the work supported upon .thebase plate.While one embodiment ofthis'invention has beenfshown and described itwill be understood that. the'in'- vention isnotlirnited thereto :andthat other embodiments may be made without departing from the spirit andscope'of .the inventionas set forth in the following claims. f
